Benign enlargement of the prostate (BEP) is highly prevalent among the male population. An estimated 50% of men have an histological evidence of BEP by the age of 50 and 75% by the age of 80. In 40-50% of these patients, BEP becomes clinically significant.

To evaluate the association between the consumption of alcoholic beverages and benign prostatic enlargement as well as male lower urinary tract symptoms, a meta-analysis of published studies pertaining to this topic was undertaken.

A total of 19 studies (120,091 men) were included. The results indicate that a daily alcohol intake of 36 grams or greater was associated with a 35% decreased likelihood of benign prostatic enlargement compared to abstainers. The lower urinary tract symptoms were not reduced. Further studies are needed to determine the mechanisms involved.
